How to list files based on sizes?

Hi,

For you experts I guess it's a small thing, for me as newbie it's a puzzle.

I need a script (Bourne shell) which lists all files in a directory which are not 0 bytes.

So if the directory /tmp has the files
file1.dat   0Kb
file2.dat   3Kb
file3.dat   0Kb
file4.dat   1Kb
file5.dat   6Kb

I expect a string back like "/tmp/file2.dat /tmp/file4.dat /tmp/file5.dat"
And it would be nice if I could pass the directory as input parameter (or via variable)

Can anyone help?
Kind regards

Hi ehout,

find <dir> type -f -size +0

remove type -f part if you entries other than files to be listed too

hiiii,
ls with -S option will give the  files  in the order of their sizes..................
if u want this in a sorted order then simply give this command

x=`ls -S /tmp`;
echo $x;

Now this x has the names of the files in sorted order of their sizes..................

Hi,

Thanx for the quick responses.
The sort order is not relevant. But the output of the function,(BTW, type -f seems to be written as -type f ) Must appear on 1 line. Can I catch it in a variable?

#say dir is ur variable which has the directory name then

x=`ls -S $dir`;
echo $x;

This would do that..............

Hai sri,

your option seems helpful,
However It lists all the files. But it should omit files of 0 bytes.

If there is a rm option that first will erase all o byte files, that's OK too.

Hai sunny,

Thanx for your input too, I'm learning a lot.

Your option actually lists what I want, but can I get these listed files on 1 line?

Reason is I have a certain mailscript and This way I can give multiple files as attachment.
